When to test

COVID Antibody Test is recommended to be used on patients with at least 3 days after onset of symptoms or 7-10 days after infection with the virus 2-4.

What to expect from a Rapid Antibody Test?

The RightSignTM COVID-19 IgG/IgM Rapid Test Cassette should not be used to diagnose acute SARS-CoV-2 infection. The Rapid COVID Antibody Test is a blood test that provides qualitative and quantitative detection of IgM and IgG antibodies against the SARS-CoV-2 in individuals suspected of COVID-19. After infection, the virus antigen stimulates the immune system to produce antibodies that can be detected in the blood. Among these antibodies, the IgM antibodies appear early and are mostly positive after 3-5 days of onset.The IgM titers then decrease while the IgG antibody potency starts to rise rapidly. During the recovery phase, the titer of the IgG antibody may increase four times or more compared to the acute phase.

What test or protocol is used for the Rapid Antibody Test?

The Rapid Antibody uses RightSignTM COVID-19 IgG/IgM. The RightSignTM COVID-19 IgG/IgM Rapid Test Cassette is a rapid lateral flow chromatographic immunoassay intended for the qualitative detection and differentiation of IgM and IgG antibodies to SARS-CoV-2 in human venous whole blood, serum or plasma, and fingerstick whole blood.
